GEAR FOR INSPECTION OF PROCESS OF ELECTRON-BEAM WELDING Russian patent published in 1995 - IPC

FIELD: welding. SUBSTANCE: gear for inspection of process of electron-beam welding has lens optically coupled through optical shutter and optical splitter of image to pickup based on charge-coupled device and pyroconic sensor, synchrogenerator. Gear is inserted with commutator and adder. Output of pickup based on charge-coupled device is linked to adder and output of pyroconic sensor is connected to input register of pickup based on charge-coupled device and adder through commutator. Output of adder is connected to unit of measurement and check and one of outputs of synchrogenerator is linked to commutator. EFFECT: provision for objective inspection of welding process, measurement of depth of penetration in absence of clearance in joint. 2 dwg
